Since the development of modern aviation at the start of the previous century, the construction of model aircraft has been a popular pastime and one which has delighted several generations of children and continues to grow in popularity. However, over the years, this hobby has become no longer just a privilege for the young and the models have become more and more advanced and it is now possible to purchase kits to make working, flying model aircraft, such as helicopters, which can be made for leisure and even to enter into competitions. There is a wide range of kits on the market to meet all levels of expertise, with basic models suitable for flying around a garden to highly advanced models for the more serious model aviator.
When embarking on constructing a remote control helicopter as a novice, several items need to be taken into consideration: the helicopter itself, choosing a suitable engine, the radio system, the tail rotor gyro, a suitable muffler and starting equipment. All of these items are readily available from any good supplier or model shop. Normally, a helicopter kit contains only a kit of the airframe, meaning that you will have to purchase the engine, radio, gyro and starting equipment separately.
There are a variety of fuels that are used to power such models. The most common being standard petroleum, however, the alcohol-based ‘Glow Fuel’ is another effective alternative but it is important to note that to use this fuel, the model requires a ‘glow engine’. The use of ‘Glow Fuel’ is beneficial due to the fact that it is odourless and considerably less volatile than petrol and also because the glow engines have a very good power to weight ratio. However, these engines produce a high-pitched sound which may prove irritating, but the use of a muffler plus the fact that these models are flown outside will counter this.
